This study cross-validated the Medical Symptom Validity Test (MSVT) in a mixed neuropsychiatric sample and examined its accuracy for identifying invalid neuropsychological performance using a known-groups design. Cross-sectional data from 129 clinical patients who completed the MSVT were examined. Validity groups were established using six, independent criterion performance validity tests, which yielded 98 patients in the valid group and 31 in the invalid group. All MSVT subtest scores were significantly lower in the invalid group (η_p²=.22-.39). Using published cut-scores, sensitivities of 42% to 71% were found among the primary effort subtests, and 74% sensitivity/90% specificity was observed for the overall MSVT. Among this sample, the MSVT component validity scales produced areas under the curve of .78-.86, suggesting moderate classification accuracy. At optimal cut-scores, the MSVT primary effort validity scales demonstrated 55% to 71% sensitivity/91% to 93% specificity, with the Consistency subtest exhibiting the strongest psychometric properties. The MSVT exhibited relatively robust sensitivity and specificity, supporting its utility as a briefer freestanding performance validity test to its predecessor, the Word Memory Test. Finally, the Genuine Memory Impairment Profile appears promising for patients with Major Neurocognitive Disorder, but is cautioned against for those without significant functional decline in activities of daily living at this time.

本研究在混合神经精神病学样本中交叉验证了医学症状有效性测试 (MSVT)，并检查了其使用已知组设计识别无效神经心理表现的准确性。检查了完成 MSVT 的 129 名临床患者的横断面数据。使用六个独立的标准性能效度测试建立效度组，其中有效组有 98 名患者，无效组有 31 名患者。无效组的所有 MSVT 子测验分数均显着降低（η _p ²=.22-.39)。使用公布的分数，在主要努力子测试中发现了 42% 到 71% 的敏感性，并且观察到整个 MSVT 的敏感性为 74%/特异性为 90%。在该样本中，MSVT 成分效度量表的曲线下面积为 0.78-.86，表明分类准确度适中。在最佳分数时，MSVT 主要努力有效性量表显示 55% 至 71% 的敏感性/91% 至 93% 的特异性，一致性子测试表现出最强的心理测量特性。MSVT 表现出相对稳健的敏感性和特异性，支持其作为比其前身字记忆测试更简短的独立性能有效性测试的实用性。最后，真正的记忆障碍概况似乎对患有严重神经认知障碍的患者很有希望，
